Is there any way to keep testing django(unittest) in terminal background?

I start using django-built-in-test tool and unittest when I create my web application.

It is kinda bothering to run python manage.py test <app_name> everytime I edit some codes.

What I want to know is whether there exist something like pytest --looponfail for django-built-in-test, which keep running test on background.

Thanks.
